Our next segment in our Ask the Expert series dives into the importance of data enrichment and its benefits across connected TV (CTV) advertising. Ask the Expert features a series of conversations with product experts where we focus on topics that matter the most in AdTech. In our latest segment, Natalia Irmin, Director of Strategic Data & Media Partnerships at a4 Advertising, joins us to chat with Experian’s SVP of Sales & Partnerships, Chris Feo.
a4 is an advanced advertising and data company that offers audience-based, multiscreen advertising solutions for local and national advertising businesses.
In their conversation, Natalia and Chris review:
- The benefits of data enrichment
- First-party data enrichment across advertising
- Data enrichment in CTV advertising
- How Experian and a4 work together
What is data enrichment?
Data enrichment enhances first-party data sets using third-party data sources. This process involves merging first-party data from internal sources with data gathered from other internal sources or from external third-party sources.
Examples of data that can be part of the enrichment process include:
- Demographic information
- Contextual signals
- Behavioral patterns
- Interests
- Purchase-intent
The more you know about your customers, the better equipped you are to reach them where they are with the right message. By enriching your data, you can enhance your messaging, provide personalized offers, and establish a loyal customer base.
First-party data enrichment across advertising
Businesses are transitioning from cookie-based third-party targeting to first-party data enrichment solutions as a result of cookie deprecation. When data enrichment is paired with internal first-party data, you can generate a more holistic customer profile.
a4 has a rich set of first-party data, based on the subscriptions to their services. a4 uses first-party data enrichment across advertising in two ways:
- Measure performance using their viewership data
- Advise their customers on where they should focus their advertising efforts based on the customer’s viewing behavior
a4 supports the enrichment of their customers’ first-party data so they can get the most out of their insights.With Experian’s privacy-first approach, a4 can continue to rely on their first-party data while protecting personally identifiable information (PII).
Data enrichment in CTV advertising
CTV advertising refers to digital advertising that appears through a streaming service during a viewer’s video content, like a movie or TV show. CTV ad campaigns allow businesses to personalize their digital marketing messages while the viewer watches content on various platforms. CTV offers a highly measurable opportunity to increase brand awareness.
Benefits of data enrichment in CTV advertising
Data enrichment provides three key benefits that can enhance targeting, personalization, and campaign effectiveness in CTV advertising.
Understand your target audience
By using enriched data such as demographic information, viewing behavior, and interests, you can gain deeper insights into your target audience, refine your targeting strategies, and create highly personalized ad experiences. Data enrichment also enables better measurement and optimization of ad campaigns, maximizing ROI.
Integrate enriched data with other marketing channels
You can integrate enriched data into CTV with data from other marketing channels. This enables the creation of comprehensive and cohesive marketing strategies that provide consistent messaging and enhance cross-channel targeting.
Enhance the value of ad inventory
Data enrichment can also benefit content publishers and broadcasters by enhancing the value of ad inventory and providing more targeted and effective advertising opportunities.
Enabling your marketers to target specific audiences will result in improved campaign performance. Through data enrichment, you can increase return on your ad spend and boost the value of your publisher’s ad inventory. a4 and Experian can help your business attract additional demand with audience enrichment. a4 uses Experian’s vast offering of audiences and combines it with Experian’s Graph. This data can later be used to activate across a4’s parent company, Altice’s owned and operated properties, as well as beyond Altice’s own footprint via premium publisher partners.

The popularity of flash sale websites with limited time & inventory offerings have grown exponentially over the two years. Online shoppers’ love for the thrill of snagging designer clothing, home décor, travel and even wine have caused visits to the category to increase 368% in July 2011 as compared to the same month two years ago and 109% one year ago. So far in 2011, Nordstrom acquired HauteLook, Amazon entered the fray with MyHabit and recently Saks Fifth Avenue announced the launch of a dedicated flash sale website after offering sale events per week on Saks’ main website. In July 2011, Zulily.com, a website offering sales targeted for women and babies/kids, captured the highest market share of visits at 16%, followed by Ideeli and LivingSocial Escapes. Amazon’s MyHabit ranked 11th, out of the 87 websites in the custom category after only 2 months in operation. Several of the major players over the past six months, the total visits to Ideeli increased 42%, Gilt.com up 14% and Nordstrom’s Hautelook up 8% for July 2011 as compared to February 2011. Total visits for MyHabit jumped 128% for July 2011 as compared to May 2011 when the website launched. The audience for Flash Sales continues to be attractive, and willing to shop – over-indexing against the online population for household incomes over $100k and creditworthy VantageScores of A and B.

The annual back-to-school season is in high gear and Moms are preparing lists and sizing up their children’s clothing and school-related merchandise needs. It’s an important time of year for retailers, as apparel, shoes, electronics, furniture, computers, backpacks and school supplies will account for the bulk of consumer spending during the back-to-school shopping season. Many marketers have historically grouped the back-to-school audience into one collective segment of households with school-age children. This leaves money on the table because there are better ways to target Moms with kids when developing a back-to-school promotional strategy. Just like the inventory of new clothes and notebooks that retailers have neatly arranged on store shelves, families with school-age children come in an assortment of sizes, shapes and colors. What is the most effective way to segment the back to school audience? This begs the question “” Marketers can always turn to basic data elements for segmentation. These include age and gender of children, number of children in the household, parent’s age, household income, and the full spectrum of school classifications (preschool, elementary school, middle school, junior high school, high school, etc.). Though a more powerful approach would be to utilize a segmentation methodology that recognizes the lifestyle and behavioral differences among households that are most likely to contain school-age kids. Here are three snapshots of family-oriented, children-centric market segments that are highly likely to be responsive to a wide variety of back to school promotional offers. All three segments have been selected from Experian’s Mosaic lifestyle segmentation solution. Babies and Bliss Description: Babies and Bliss represent the premier lifestyle for large families in America. With a majority of households containing at least five people, this segment is a haven for large broods living in new suburban subdivisions. Parents in this segment tend to be in their 30s and 40s. There is a wide range of kids in these households, from preschoolers up to those in high school. There is also money in this segment, reflecting the high educations and low six-figure incomes that come from dual earners employed in professional and technical occupations. Some key traits of Babies and Bliss households include upscale tastes, large families, well-educated, conservative views, financially-savvy, convenience, and power shopping. Implications: Given their large families, it's not surprising that Moms from Babies and Bliss households are value-conscious shoppers who seek appealing deals for quality merchandise. They carry coupons, like to comparison shop when buying expensive items and head to the clearance rack first whenever they buy clothes, which tend to be conservative in style. In the mall, these Moms follow their children's lead but also remain very open to consider generic store brands rather than high-priced name brands. They like to shop (it's practically a sport) and are happy to open their wallets at department stores, specialty shops, catalogs and online sites. They especially pride themselves in being very Internet-literate. With their jobs, kids and errands, they appreciate the convenience of shopping online and are receptive to email ads, sponsored Websites and Web page links. Families Matter Most Description: A fast-growing segment, Families Matter Most consists of young, middle-class families in suburban locations leading active, family-focused lives. Nine out of ten households have kids (nearly two-thirds have multiple kids). These young, middle-class families have settled into a landscape of recently built subdivisions. Many adult household members are urban exiles who've sought a suburban setting with room for kids to grow. They are proud of their new homes, schools and shopping centers, where they can find everything they need just a short drive away. Families Matter Most distinguish themselves by having adopted attitudes and routines to help them effectively juggle the responsibilities of work and child-rearing. Some key traits of Families Matter Most households include sprawling families, family values, casual perspectives, price-sensitivity, credit revolvers, conformists and risk avoidance. Implications: Families Matter Most are casual in their attitude except when it comes to their children. They take their role as parents very seriously, which they describe in conservative terms. They avoid risks and feel little need to make a statement with their possessions. As shoppers, Moms from Families Matter Most households are price-sensitive consumers who look for discount stores that offer durable and comfortable fashion. They are worried about spending money impulsively and try to be informed consumers. Most are happy to wear last year's fashions and they tend to zero in on a few stores that carry the affordable brands they prefer. With their growing families they shop most often at discount and mid-market national chains including Target, Walmart, Kohl's, Toys R Us and Old Navy. Cul de Sac Diversity Description: Cul de Sac Diversity consists of ethnically diverse, middle-aged couples with school-aged children. This segment has an above-average concentration of Hispanic and Asian household members. Nearly one-third of Cul de Sac Diversity adult members are foreign-born. They are three times more likely to be bilingual compared to U.S. adults overall. These upper-middle-class households are well on their way to achieving the American dream. They believe in home and family, but also recognize the need to work to get ahead. They look at their work as a career, not a paycheck, and are willing to give up family time in exchange for the opportunity to advance in their careers. Some key traits of Cul de Sac Diversity households include ethnically diverse, bilingual, mainstream mindset, community-minded, tolerant and career-focused. Implications: Moms from Cul de Sac Diversity households like to shop with friends and family members in order to get everyone's opinions on potential purchases. As consumers, they often seek status and recognition through their possessions. They are attracted to designer labels and sometimes spend more on clothes than they can truly afford. They like going to mainstream retailers to shop for their children including Kohl's and Macy's as well as sporting goods chains such as Dick's Sporting Goods and Sports Authority. They are only moderately receptive to online advertising. Deploying a back to school marketing strategy that treats all households with school-age children as one undifferentiated market is like creating a basic lesson plan and applying it to all grade levels of a one-room schoolhouse. Instead, marketers are encouraged to study their target audience more closely. With key insights in hand, they will have acquired the necessary prerequisites for graduating to a strategy that acknowledges the shopping characteristics and needs of a diverse and potentially lucrative audience of back-to-school Moms and their children.

Segmentation Layering For many marketers, segmentation is like breathing – it comes naturally and is a part of everything they do. To better connect with your target audience, use a good segmentation system with multiple layers that provides a breakdown of essential information while tying in lifestyle and transactional data. Consider marketing to parents. The most basic information includes demographics such as age, income, presence of children, etc. Add to that lifestyle information – the family has two working parents who rely heavily on the Internet for research and purchase convenience. The transactional data can really set apart where a parent falls on the parenting lifecycle. For example, is the parent still purchasing diapers and feeding supplies for their infant or bedding, towels and a coffee maker that might indicate their “baby” is headed to college? Both parents may look similar when comparing demographic and lifestyle information but the transactional data differentiates their needs. According to Experian Marketing Services: Parents use the Internet far more than the average American Moms are 34% more likely to buy products online and 33% more likely to participate in a blog than the average adult. "Marketers are targeting more carefully based on both the parents' life stage and consumer behavior,” says Jan Jindra, senior product market manager at Experian Marketing Services. “Younger parents, and those of smaller children, have different information needs than parents of older or college-age children. It's not only the life stage they're in, but the lifestyle," Jindra says.
